The problem is getting enthusiastic people who can volunteer and commit to the require amount of effort. Even if it's just making a mod, rather than a full game, it will take some serious amount of work to get something as realistic as what the members here are proposing.
HL SDK is free for mod-making, I think. (as long as the mod itself is free)
The cost for Serious Engine is huge though. Although I'm not sure about costs for mod-making, rather than standalone games.
